[0031] Example

[0032] In order to solve the problem that the copper foil single-piece cutting machine in the prior art has low working efficiency and cannot ensure the consistency between the copper foils, reference Figure 1 and Figure 2 As shown, the present application discloses a double-roll copper foil cutting and stacking device, including a double-roll sending mechanism 10, a cutting mechanism 20, a stacking conveying mechanism 30 and a material pulling mechanism 40;

[0033] The double-roll sending mechanism 10 includes a material rack 11, an upper material discharge assembly 12 and a lower material discharge assembly 13. The upper material discharge assembly 12 and the lower material discharge assembly 13 are respectively arranged on the upper and lower sides of the material rack 11. The material rack 11 is equipped with four guide assemblies 14 for guiding the upper material discharge assembly 12 and the lower material discharge assembly 13 to discharge materials. The four guide assemblies 14 are set in pairs. In specific implementation, the copper foil sent by the upper material discharge assembly 12 and the lower material discharge assembly 13 will be guided by two guide assemblies 14 and then stacked together;

[0034] The cutting mechanism 20 includes a cutting frame 21, a material unloading traction assembly 22 and a cutting assembly 23. The cutting frame 21 is arranged on the left side of the material frame 11, the material unloading traction assembly 22 is arranged on the right side of the cutting frame 21, and the cutting assembly 23 is arranged on the left side of the cutting frame 21. In the specific implementation, the material unloading traction assembly 22 pulls the copper foil sent by the upper unloading assembly 12 and the lower unloading assembly 13 to the bottom of the cutting assembly 23 and leaks it from the left side of the cutting assembly 23.

[0035] The stacking and conveying mechanism 30 includes a base frame 31, a lifting drive assembly 32 and a conveyor 33. The base frame 31 is arranged on the left side of the cutting frame 21, the lifting drive assembly 32 is arranged above the base frame 31, and the conveyor 33 is connected above the lifting drive assembly 32. Before the double-roll copper foil cutting and stacking equipment is implemented, the operator first places an empty pallet on the conveyor 33. Each time the copper foil is stacked, the lifting drive assembly 32 will drive the conveyor 33 to descend to a set height. When the copper foil on the conveyor 33 is stacked to a set height, the conveyor 33 will send out the pallet on the conveyor 33 (the operator can set a trolley outside the base frame 31 in advance to receive the pallet).

[0036] The material pulling mechanism 40 includes a transverse driving component 41, a linear guide 42 and a material clamping component 43. The transverse driving component 41 and the linear guide 42 are arranged above the front and rear sides of the conveyor 33. The material clamping component 43 is connected to the transverse driving component 41 and the linear guide 42 toward the cutting frame 21. When the cutting component 23 cuts the copper foil, the transverse driving component 41 and the linear guide 42 will cooperate to drive the material clamping component 43 to move right to the cutting component 23 to clamp the leaked copper foil, and then the transverse driving component 41 and the linear guide 42 will cooperate to drive the material clamping component 43 to move left to pull the copper foil out of the set length. After that, the cutting component 23 can perform the cutting operation, and after the cutting component 23 completes the cutting of the copper foil, the transverse driving component 41 will continue to drive the material clamping component 43 to move right with the linear guide 42 to stack the cut copper foil on the pallet.

[0037] In order to prevent external dust from falling into the double-roll copper foil cutting and stacking device, the present application also includes a dust cover 50 for covering the entire device, so that the user can prevent dust from entering and avoid unnecessary pollution to the copper foil.

During the specific implementation, the first cylinder 221 drives the wheel frame 222 to descend so that the pressure wheel 223 cooperates with the guide wheel 225. When the feed motor 224 drives the guide wheel 225 to rotate, the guide wheel 225 will extrude the copper foil with the pressure wheel 223.

Under the drive of the worm gear lift, the conveyor 33 can realize lifting movement.

[0046] In addition to the above structure, in order to prevent the stacked copper foil from being taken away when the pulling mechanism 40 is running, the present application also provides a flip pressing mechanism 60 between the stacking mechanism and the cutting mechanism 20, and the pressing mechanism includes a pressing arm 61, and the pressing arm 61 is provided with a plurality of U-shaped notches 611 on the side facing the stacking conveying mechanism 30, and a flip pressing block 63 extending outward is hingedly connected to the upper part of the inner part of the plurality of U-shaped notches 611, and a hinge block 631 is provided at the bottom of the flip pressing block 63, and a plurality of U-shaped notches 611 are hingedly connected to the upper part of the inner part of the plurality of U-shaped notches 611.
